Question

the captain of the cricket team of 11 members is26 years old and the wicket keeper is 3 year older. if the ages of these two at excluded,the average age of the remaining player is one year less than the average age of the whole team. what is the average age of the team​

Answer 1

Step-by-step explanation:

avg age of wk and cap

26+29/2=27.5

26.5 is avg age of whole team

then 26.5+27.5/2=54/2=27

the avg age of whole team is 27

Answer 2

Answer:

23

Step-by-step explanation:

This is a question on mean

the number of members=11

the captain of the team is 26 while the wicket keeper is 3 years older(26+3)=29

therefore average of team=(26+29+9 other people)/11

therefore,

lets call other people,'x'

therefore,average of team= (26+29+9x)/11

the average without captain and wicket keeper is (9 other people/9)=(9x/9)

it is said that the average without captain and wicket keeper is one less than the average of team, therefore  the average without captain and wicket keeper = than the average of team -1

((26+29+9x)/11)-1=(9x/9)

this gives you 22

x=22

substitute it in "the average of the team" equation

(26+29+(9*22))/11

this gives you 23
